' My invention embodies a horizontal base or 7 body comprisingorsupporting the mold or pan with a cover or movable follower-plate andhaving at each end a short upright post Y n 'soasvo.

To all whom it mdy concern."

- Be it known that I, HENRY F.-SriAW,of 3 Boston, inthe-countyfofsuffolkand State of.

'Massachusetts, have invented certain new and useful Improvements inAutomatic Pressesyof,

whichthe following is a specification.

The objectof this invention is to provide a ive construction adapted.for various household purposes and operating withoutla pressure-screw,but by a peculiar leverage utilizing its own weight and thatof thematerial to produce, an'increasing pres-- or otherfulcrum in combinationwith actuating-levers formlng supportlng-legs having a spreading act1onand so fulcrumed on said posts that the short armsof said levers pressupon the follower-plate, while the much longer arms rest terminally onthe floor or table.-

These lower ends are broadened to form supporting-feet, and each has aroller to facilitate movement as the legs spread with compression of thematerial, thus increasing the leverage.

"In the drawings, Figure 1 is a top plan of. my improved press, shown asin use. Fig.2 is a vertical central section indicating position of partsas the material becomes somewhat compacted. Fig. 3 is aview in side.elevation, showing the parts detached.

The numeral 5 represents-a flat base, preferably an openi-work castingformed with upright fulcrumposts'6, extending obliquely outward. Asuitably-shaped mold or pan 7, tapering somewhatdownwardly, is adaptedto rest on the base 5yand 'is provided with a loose-fittingfollower-plate 8, havinga knob or handle 9. The material to be treatedwill be placed in the mold and covered by said plate. The mold or panmay be secured to or made integral with the base, or, in other words,the base mayhave raised sidesand ends withcapacity. to containthematerial to ient to have Fig. 3.

. -.To the top of posts'6 the actuating-levers a e pivoted at suchintermediatepoint as to givea leverage of about threeto one. The

short arms 10 of theselever's are so shaped as Specification of LettersPatent. Application fiieammh 9, 1905. seen No. 249,212.

of pressure,'and such longarm 11. extends downw'ardlyand obliquely whenin use andspreadsatbottom to form a transverse foot Yofconsiderablebreadth. Each foot is furnished with a' terminaI roller 12to facilitate the spreading actionwhen the press is in use.

' A similar roller 13 may be applied to the upper end ofarm 10, asshown. The drawings '1 show the. preferred construction.

ating leversare of skeleton form, each made The actuof two steel rods.bent to. the desired shape andunited laterally,their extreme ends turnedI inwardly to enter and form bearings for the tubularrollerslQ 13. Eachlever may be cast of a single piece or may consist 'of-a single rod, itsmiddle portion forming the foot and the roller12 being placed thereonbefore the rod is bent to form the lever. A metallic cross-piece 14'connects the spread rods transversely near the foot. They are also heldin close contact by the fulcrum-plate 15, formed of heavy sheetmetal-folded tightly around,

the rods, its ends projecting each side. of the tip of the fulcrum-post6 or into a recess therein and perforated to receive the rivet or'standabout vertical, as in Fig. 3, and the mold or 'pan 7 containingmaterial to be pressed is placed onthe base 5 and covered with plate 8.Then on spreading the lower arms 11 of the actuating-levers the tips ofarms 10 or the rollers 13 thereon'will bear downwardly on the topof saidplate and exert a pressure proportionate to the weight of the press andmaterial and to the relative length of the lever- -arms, such pressureincreasing automatically as rollers 12 spread and, the arms 11 becomemore nearlyhorizontal. 4 v v I claim asmy'invention 1. -Apressin'g'apparatus comprising abody or'base' to receive the material tobe treated I and a relatively movable cover forsuch material, incombination with actuating-levers pivotally connected to the base, theirlong arms extendingobliquelyidownward and outward, forming supports, andtheir short arms bearing terminally on said cover, for the purpose setforth.

2. The described automatic press comprising a horizontal base or bodywith terminal fulcrums, a mold or pan to receive the material and aloose-fitting cover therefor, in combination with actuating-levers,pivoted on said fulcrums, their long arms forming supporting-legs whichextend downwardly and obliquely outward and are provided with transverserollers, while their short arms project inwardly and bear downwardly onthe cover, for the purpose set forth.
